Abstract
A total of 22 cities in Chile were analyzed focusing the development of a 30 MW Photovoltaic Solar Plant using RETScreen software. Results of the study indicate that Calama City presents interesting results, with a Capacity Factor of 34.0% and an Energy Production of 92523 MWh. However, with a discount rate of 12% and an evaluation of 30 years, a Net Present Value (NPV) of −67×106 USD and an Internal Rate of Return (IRR) of 7.0% were obtained due to the high investment cost. Applying a 40% incentive in Calama City, the NPV reaches 11×106 USD, with an IRR of 13.7%, thus obtaining positive financial results.Sensitivity analysis, without the incentive applied, considers the variation of ±30% for five parameters, indicating that the initial cost and the electricity export rate significantly influence the results of the project. A risk analysis was performed on these parameters indicating that an NPV≤0 and an IRR≥12% were reached for 94.0% and 7.0% of the projects, respectively considering the initial cost. Analyzing the electricity export rate, only 5.0% of the projects had positive results for NPV and only 4.0% of the projects meet the criteria established for the IRR.
